  • Each clip can be configured to interlock (e.g. elastically), in the assembled state of the modular lateral bolster, with a respective locking recess arranged on the upper surface of the main base.
  • the assembly of the modular squab cushion to the seat structure can be implemented on a final assembly site, while manufacturing of the modular squab cushion itself, and in particular the assembly of its various components, implemented on a site distinct from the final assembly site.
  • the manufacture of the modular squab cushion may comprise, initially, the pre-assembly of the modular lateral bolster by assembling the lateral base, the lateral padding and the lateral covering, and on the other hand, the pre-assembling of the central padding on the main base and the main covering that covers the central padding by fastening it to the main base. It is then possible to fasten the modular lateral bolster (or the two modular lateral bolsters) to the main base.
  • the assembly between the modular cushion and the seat structure as well as between the modular bolster and the modular cushion can also allow rapid disassembly, and advantageously a disassembly/removal of the modular cushion and/or the modular lateral bolster without disassembling the seat structure from the floor of the vehicle.
  • the present disclosure also relates to a method for maintaining a seat assembly according to the present disclosure, comprising disassembling at least the modular lateral bolster from the main base without disassembling the modular squab cushion from the seat structure by the following implementation:
  • Comparative vehicle seats use a seat design in which the various components of the seat to be assembled at a site, typically according to just-in-time manufacturing also referred to by the abbreviation “JIT”.
  • the structure of the comparative seat of a motor vehicle comprises a metal seat structure which may comprise a squab structure and a backrest structure.
  • the comparative seat structure may comprise:
  • the squab of such a seat may further comprise a squab padding, typically expanded polyurethane foam, and a trim covering that covers the foam squab padding.
  • the seat may further comprise at least one lateral bolster formed of a lateral padding, typically expanded polyurethane foam, for example arranged on either side of the squab cushion or forming a single block with the squab cushion, the assembly being covered by the trim covering.
  • the squab of a seat tends to wear over time, which can result in wear of the trim covering/padding, or even a tear in the trim covering and/or the padding.
  • squab that comprises a support base, often plastic, padding and a cover element, which can be preassembled, very often on a site distinct from the final assembly site, typically with more competitive labor costs.
  • the final assembly is obtained by fastening the modular squab cushion, which is formed from a single piece, on the squab of the seat, quickly during the final assembly.
  • the modular squab cushion which is formed from a single piece, on the squab of the seat.
  • During maintenance for example when a component of the squab is worn, it is possible to remove the squab module in full, and to replace it with a new squab module.
  • Such a solution is particularly satisfactory during the implementation of the final assembly due to an improved manufacturing time during final assembly, it requires, during maintenance, changing the entire squab module, and even if only part of the module is damaged.
  • This comparative solution is however not completely satisfactory, and in particular during final assembly, in that it uses the assembly of numerous module segments on the squab structure, in particular for the squab, which increases the seat-manufacturing cycle time at the final assembly site.
  • the present disclosure improves the situation.
  • a modular squab cushion configured to be attached to a squab structure, the squab structure being configured to removably attach the modular squab cushion, the modular squab cushion comprises in the assembled state:
  • such a configuration of a modular squab cushion comprising at least one modular lateral bolster allows quick mounting on a squab structure, in that the modular squab cushion, a single-piece component, in the assembled state can be quickly fixed to the metal structure of the seat, in particular by forming all the segments of the squab, namely not only the central portion typically forming the medallion of the squab, but also the two lateral parts.
  • the two lateral parts typically higher along a vertical component relative to the central portion, have the function of laterally holding the occupant onto the squab.
  • Such a configuration also facilitates the maintenance of the squab, and without it being necessary to disassemble the structure of the vehicle floor seat.
  • such a configuration allows easy mounting and/or maintenance of the lateral bolster, a modular component independently of the central padding and the central trim covering which remain fixed to the main base, itself attached to the structure of the seat.
  • the present disclosure is in particular born from the inventors' observation that the lateral segment of the squab is often the segment of the squab that wears out most quickly, and typically more quickly than the central segment of the squab.
  • the present disclosure thus allows this quickly-wearing segment to be changed, only without it being necessary to change the central portion of the squab, and in particular the central padding and the central trim covering which remain attached to the main base, itself attached to a seat structure.
  • the mechanical interface system comprises:
  • the first locking part comprises a strike and the second locking part comprises a latch, the strike and the latch being opposite at the end of pivoting into B.
  • a locking of the modular lateral bolster on the main base is obtained as follows:
  • the mechanical interface system comprises a plurality of first coupling parts arranged on the lateral base and a plurality of second coupling parts arranged on the main base, the first coupling parts and the second coupling parts cooperating by interlocking, and wherein the mechanical interface system is configured to allow the fastening of the modular lateral bolster on the modular squab cushion as follows:
  • the lateral base comprises a peripheral edge comprising a groove and the lateral trim covering is provided with a system for fastening along at least one end part of the lateral trim covering, the fastening system being configured to penetrate the groove while fastening it.
